sounds like you answered your own question.


More likely to be something along the lines of an air metering problem. Spark plugs will generally wear down to little tiny nubs before letting you down. MAF? Is the "Check Engine" light flashing? Could be a fuel problem as well. I doubt replacing spark plugs will fix anything.
